    d: Fix internal compiler error: Segmentation fault at gimple-expr.cc:88

    Because complex types are deprecated in the language, the new way to
    expose native complex types is by defining an enum with a basetype of a
    library-defined struct that is implicitly treated as-if it is native.
    As casts are not implicitly added by the front-end when downcasting from
    enum to its underlying type, we must insert an explicit cast during the
    code generation pass.

    gcc/d/ChangeLog:

            * d-codegen.cc (underlying_complex_expr): New function.
            (d_build_call): Handle passing native complex objects as the
            library-defined equivalent.
            * d-tree.h (underlying_complex_expr): Declare.
            * expr.cc (ExprVisitor::visit (DotVarExp *)): Call
            underlying_complex_expr instead of build_vconvert.

    gcc/testsuite/ChangeLog:

            * gdc.dg/torture/pr106623.d: New test.
